I recently bought my first colecovision, bother controllers were not functioning properly, the right fire button on both controllers were not working and the joystick on one of them wouldn't recognize movement to the right. I cleaned the contacts for the joysticks and used electrical contact cleaner on the trigger buttons. One of them is working great and the other doesn't do anything at all now. Any suggestions? Also, the system itself, a lot of times the games start but have graphical errors, i turn the system off and take the game out and put it back in sometimes a couple times and it eventually works fine, is this common or is there something I should do to fix this? I already cleaned the game cartridges and the game port on the system. Any suggestions would be greatly appreciated. Thank You.
